Ok, before writing the above, I had installed the stock debian
kernel-image-2.4.20-3-686, along with alsa-modules-2.4.20-3-686, alsa-base,
alsa-headers, and alsa-utils. I had not run alsamixer to unmute the sound.
I have now done so, but still no luck.
alsamixer settings:
Master: 52
Master Mono: 52
3D Control - Center: 53
3D Control - Depth: 53
3D Control - Switch: 0 (won't go up)
PCM: 52
Surround: 52
Surround Down Mix: 0 (won't go up)

As my speakers only have one jack and there are two places for speaker jacks
on the back of the MB, I'm not certain which one I should use. With the
volume up on the speakers, I get static touching either one with the jack,
but I also get no sound with it plugged into either one. I picked the darker
green one, which is closer in color to the speaker jack.
As I don't know much about how sound works in gnu/linux, it is possible I'm
not testing it correctly. Additional info is that I am running KDE. There's
no sound from it either, but I'm not sure how that might affect my ability to
play sound from the command line. I figure I should get sound working from
the command line before working on KDE.
